Strangeness Production at SIS measured with HADES. (arXiv:0911.0516v1 [nucl-ex])

n this paper we review the recent results on strangeness production measuredby HADES in the Ar+KCl system at a beam energy of 1.756 AGeV. A detailedcomparison of the measured hadron yields with the statistical model is alsodiscussed.
